EBECRYL® 450

EBECRYL® 450 is a fatty acid modified polyester hexaacrylate. Because of the special structure of the backbone and the high acrylic functionality, EBECRYL® 450 provides the proper hydrophilic-lipophilic balance necessary for lithography, combined with high reactivity when cured by ultraviolet light (UV) or an electron beam (EB). Lithographic inks based on EBECRYL® 450 display outstanding printing qualities, including excellent ink transfer, good dot definition, and proper tack and rheological properties.

Performance Highlights

EBECRYL®450 is characterized by:

  • Rheology suited for lithographic inks
  • Fast cure response
  • Good pigment wetting
  • Good lithographic behavior

 

UV/EB cured products containing EBECRYL®450 are characterized by the following performance properties:

  • High abrasion resistance
  • Good hardness
  • Good solvent resistance

The actual properties of UV/EB cured products also depend on the selection of other formulation components such as reactive diluents, additives and photoinitiators.

EBECRYL®450- Viscosity Reduction - 1

    EBECRYL®450
  • Graph I show the viscosity reduction of EBECRYL 450 with the reactive diluents EBECRYL 40(1), EBECRYL 140¹ (ditrimethylolpropane tetraacrylate), EBECRYL 150¹ (ethoxylated bisphenol A diacrylate), and OTA-480.
  • Although viscosity reduction can be achieved with non-reactive solvents, reactive diluents are preferred because they are essentially 100 percent converted during UV/EB exposure to form a part of the coating or ink, thus avoiding solvent emissions.
  • The specific reactive diluents used will influence performance properties such as hardness and flexibility.
  • Graph II illustrates the change in viscosity of EBECRYL 450 with increasing temperature.

Storage & Handling

Storage and Handling Conditions
  • Care should be taken not to expose the product to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or acids.
  • This might cause uncontrollable polymerization of the product with the generation of heat.
  • Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers.
  • Procedures that remove or displace oxygen from the material should be avoided.
  • Do not store this material under an oxygen free atmosphere.
  • Dry air is recommended to displace material removed from the container.
  • Wash thoroughly after handling.
  • Keep container tightly closed.
  • Use with adequate ventilation.
